CAS Login Will Only Route To The Same Node in a WebLogic Clustered Environment Despite Proper Load Balancer and Web Server configurations
Last updated on OCTOBER 07, 2016
Applies to:Oracle WebCenter Sites - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
URL is routed to the same cluster node for each request instead of load balancing to other cluster members. For example, there is the following configuration:
LB --> 3 Web Servers --> 5 Sites Nodes
- Load Balancer is configured correctly
- Web Servers are configured correctly, including the rewrite rules
- CAS configurations are setup correctly for the clustered Sites instances
Symptom: Attempt to access www.example.com, client is redirected to Sites Node 1. Even when Sites Node 1 is shutdown, then any attempt to access www.example.com, client is still redirected to Sites Node 1 but receives a 404 error and NOT the expected Request Timed Out error.
